Gas or vapor burner.



UNITED STATES PATENT OFFICE;

HERBERT HARTLAND LYTLE, OF LONDON, ENGLAND..

GS OR VAPOR BURNER.

SPECIFICATEON fonning part of Letters Patent No. 696,061, dated March 25, 1902.

Application filed January 19, 1901. Serial No. 43,871. (No model) To all whom, it' may coi Learn,.-

Be it known that I, HERBERT HARTLAND LYTLE, engineer, a subject of the Queen of Great Britain, residing at 55 Hunter street, London, England, have invented certain new and useful Improvements in Gas or Vapor Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appert'ains to make and use the same.

This invention relates to improvements in gas and vapor burners generally; but such improvements are more especially applicable to gas and vapor bu rnersin which the flame is maintained by the supply of gas or vapor produced in a generator disposed aboveand heated by the said flame, which burners are esp cially applicable for use in the furnaces of] steam-generators and the like.

The object of my invention is to provide a burner of simple Construction which shall not be liable to be easily extinguished and which shall insure perfect combustion of the gas or vapor, and thereby not only avoid smoke and unpleasant smell, but obtain the maximum heating eftect of the oil or other liquid fuel consumed.

Figure l of the accompanying drawings is a vertical section of myimproved burner, and Fig. 2 is a horizontal section on line X X of Fig. 1. i u

Similar letters denotelike partsthroughout the drawings.

a is the burner-orifice, to which the gas or vapor is conducted from the generator b through the vertical passages oand horizontal passages d. The gas or vapor is projected in a more or less finely-divided stream orstreams through suitable perforations or openings at the said burner-orifice a. These perforations or openings may be drilled in the upper end of the orifice branch e; but I prefer to employ a valve f, as shown in the drawings. This valve f has a central hole g, which constantly comnunicates with the horizontal passages d, so as to supply a limited quantity of gas or vapor to support combustion even when the valve f is closed.

z is the burner proper, which is screwed onto the orifice branch e, as shown. The stem h of the valve f is extended downward 4 direction, as shown.

into the recess t' and is f urnished at its lower end with a spring j and adjustable screw-unt k, whereby the pressure required to open the valve f may be regulated at pleasure.

Z is a plate forming a gas and liquid tight cover for the recess i, which is thereby kept charged with' oil, which serves to keep the spring j and surrounding parts cool.

m is an annular trough for the reception of spirit when starting the burner in a manner well understood in connection with this class of apparatus. V

n is a hollow truncated cone supported at a suitable distance above the burner-orificea by means of the standard o or by other convenient means, being preferably adjustable as to height by means of the screw-nuts 19 and q.

r is an annular battle or flame dividing plate, the diameter of the central opening of which approximates more or less closely to the internal diameter of the upper and smaller end of the hollow truncated cone n, the inner edge s preferably projecting in a downward The generator b is of any suitable Construction, to which oil is ad mitted from the oil-pipe u, which is prefer ably coiled, as shown, so as to vaporize the oil more or less before it enters the generator.

u When the'burner is in operation, the gas or vapor from the generator b passes to the burner z either through the central hole gin the valve only or also through the opening of the valve f, according to the pressure of the gas or vapor behind the said valve. The gas or vapor is projected through the burner z 'upward into the hollow truncated cone n. On leaving the upper end of the cone n the gas or vapor flame is divided, the central portion thereof passing through the opening in the annular baffle or flame-dividing plate r, striking the under side of the generator b and being deflected outward thereby,. while the outer portion of the said flame impinges on the inner edge s of the annular battle orflamedividing plate r and is defiected outward by the surface `of the under side of the said annular baffie or flame-dividing plate. The two portions of the flame meet and more or less intermingle after having passed the outer circumference of the annular baffle or flame-dividing plate r, and a more perfect oombus- IOO tion of the vapor orgas is thereby insured than heretofore.

In some cases the valvefmay be dispensed with and any convenient number of holes be provided in the upper part of the orifice branch e for the outlet of gas or vapor.

I claiml. In an apparatus for generating and burning gas or vapor-,the combination of the burner z with a valve f, an adjustable cone 'n above the burner, a generator b above the cone, a Conduit extending from the generator to the bnrner and an annular defieetor-piate 7 having a central opening with a downwardly and inwardly projeeting part s extending about the opening, said downwardly-projecting part together with the main part of the defiectorplate serving to defiect a portion of the flarne ontwardly against the Conduit, substantially as described.

2. In combination in an apparatus for generating and burning gas or vapor, a burner a', an adjustable cone n above the burner and a defiector a' above the cone, said deflector having a central opening with a downwardly and inwardly projecting part s about said opening, the said projecting part together with the horizontal part of the defiector serving to deflect a portion of the flane outwardly, substantially as described.

3. In conbination in an apparatus for generating and burning gas or vapor, an adjustable oone n, and a defiector-plate above the same having a central opening with a downwardly and inwardly inclined part s extending about the opening, said part with the horizontal portion of the deflector-plate serving to defiect a portion of the flame outwardly, substantially as described.

In witness whereot' I have hereunto set my hand in presence of two witnesses.
